How can dust generation be avoided when adding powdered activated carbon? Does your factory have any good methods?

When adding powdered activated carbon, a closed-system addition method or a wet addition method can be used to avoid dust generation. Specifically, for closed-system dosing, a sealed device must be installed on the equipment; powdered activated carbon is fed into this sealed device, and the gas inside it is then treated and purified through an exhaust system. This method can effectively prevent environmental pollution and health problems for workers. Wet addition involves spraying water or injecting it into the water during the addition of powdered activated carbon, in order to moisten the powder and reduce the likelihood of dust dispersion. This method is relatively simple and easy to implement, as well as cost-effective. Our company has also adopted the above methods for adding powdered activated carbon, achieving good results while also meeting environmental protection standards. .

A negative pressure pipeline is installed above it, and a filter bag collector is connected to this pipeline; the filter bags are regularly purged with nitrogen.
